i86 THE ENTOMOLOGIST. 



thorax and scutellum ; mandibles very broad and short, quadridentate, 

 not counting inner corner ; facial quadrangle longer than broad, 

 xjrbits converging below ; clypeus very strongly and densely punctured, 

 not keeled, the lower margin with low widely separated median 

 tubercles ; basal half of metathoracic area finely rugose, apical part 

 smooth (though not polished) and somewhat shining, in complete 

 contrast ; tegulae black with obscurely reddish margins ; wings dusky ; 

 stigma piceous ; tarsi with conspicuous yellowish-white hair on outer 

 side, fulvous or inner ; abdomen with very little hair, but the hind 

 margins of segments have extremely narrow but distinct creamy- 

 white hair-bands ; segments 2 to 4 with deep transverse impressions; 

 sixth segment rapidly descending, concave in profile ; ventral scopa 

 entirely creamy-white. 



Hab.— Tokyo, Japan, August 30th, 1906 {Sasaki, 151). This is 

 quite unlike the previously known Asiatic species, being a member of 

 the North American subgenus Oligotropus. Compared with the 

 type of Oligotropus {M. campanulcB, Kob.) it differs by the narrower 

 face, more robust manibles, more coarsely punctured thorax, more 

 closely and finely punctured abdomen, and much broader hind basi- 

 tarsi. The broader type of hind basitarsus is found in the Californian 

 M. angelarum Ckll. 



Andrena alopex, n. sp. 



? . Length about 12 mm. ; black, the abdomen very faintly 

 greenish ; head and thorax with abundant long fulvous hair, bright 

 fox-red on occiput and thoracic dorsum, some dark hair on vertex ; 

 head very broad, facial quadrangle broader than long ; facial foveas 

 very broad, reddish-brown ; mandibles entirely black ; malar space 

 almost obsolete ; process of labrum very broad and rounded ; clypeus 

 shining, strongly punctured, without a distinct impunctate band ; 

 antennae black, third joint about as long as next two together ; 

 mesothorax entirely dull, with shallow hardly noticeable punctures on 

 a microscopically cancellate surface ; disc of scutellum polished and 

 shining, with irregular distinct punctures ; area of metathorax dull 

 and granular, more or less rugose basally, not well defined ; tegulae 

 fulvo-ferruginous ; wdngs somewhat dusky, with a yellowish tint, 

 stigma (which is well developed) and nervures ferruginous ; b.n. 

 meeting t.m. ; second s.m. broad, receiving first r.n. a little beyond 

 middle ; legs more or less reddish, but dark, with pale hair ; hind 

 tibial scopa pale-golden, brown near base above , abdomen shining, 

 with minute feeble punctures ; second segment depressed about two- 

 fifths ; first two segments with long pale hair ; segments 2 to 4 with 

 conspicuous entire creamy-white hair-bands ; caudal fimbria reddish- 

 brown or chocolate. 



Hab.— Japan (no exact locality), two from Dr. Sasaki (148). 

 Superficially, this looks almost exactly like A. extricata, Smith 

 (fasciata auctt.), but it is distinctly less robust, and has nothing of 

 the fine regular abdominal punctures of extricata. It is not very 

 close to any described Japanese species ; by the faintly metaUic 

 abdomen it may be compared with A. consimilis, Alfk., by the bright 

 red thoracic hair with A. biscutata, Perez,
